Filed: 1982-09-16
Abstract: PURPOSE:To attain quick and accurate search, by stopping a tracking servo in the shifting state of a pickup by an output driving signal of a counting means stopping the shift of the pickup in response to the distance data. CONSTITUTION:Position calculating circuits 158, 159 calculate the distance data with the absolute address of the pickup 142 of a present address memory 153 and the absolute address of the objective position outputted from an adder 157. An output of a subtraction circuit 160 is the distance data between the pickup position and the objective position.

Title: Preparatory discharge method of ink jet recorder and preparatory discharge control circuit thereof
Inventor: ISHIWATARI MASUMI
IPC: B41J2/18
Filed: 1992-06-19
Abstract: PURPOSE:To suppress the power consumption in clocking by a simple structure by a method wherein charge or discharge to a capacitor is carried out in case of an off state of a recorder or its pause state, and a number of preparatory discharge operations of ink is controlled in response to electric potential of the capacitor when the recorder is started again. CONSTITUTION:When input of a key is not performed for a specific time, an OFF timer counter provided to a RAM 4 is processed by +1. When an OFF key is pushed down or the timer counter makes a carry be generated, the timer counter stops clocking operation and turns OFF. At that time a capacitor C is gradually charged via a high resistance R1 connected to a cell +V. Thereafter, when an ON key is pushed down, a discharging port 11-1 being an open drain of an output port group 2 is turned ON for a specific time to discharge a part of the charge stored in the C via a resistance R2. Its electric potential is taken in with an input port 2, stored in the RAM 4 via a data bus 10, and treated by a preparatory discharge processing until the value becomes zero.

Filed: 1984-07-31
Abstract: PURPOSE:To improve the resolution without losing the linearity by converting a low-order nL bit data of an N-bit input data into a PAM wave and obtaining a converted output synthesized with a PWM wave of a high-order nH bit data. CONSTITUTION:High-order bit data D1, D2 of the input data DIN are inputted to terminals 1, 2 and FF18, 16 output a PWM wave in response to the D1, D2. In this case, an output pulse of the FF18 is wider than an output pulse wave of the FF16 by 1 LSB's share at all times. The output of the FF18 is gated low-order bit data D3-D5 through AND gates 25-27. Constant current sources 122-124 of a PWM wave output section 100 are set so that each current value corresponds to each weight of the D3-D5. Thus, the output section 100 adds and synthesizes the PWM waves P1-P4 whose height of pulse is decided by the said current value and whose pulse width is decided by the operation of switches 111-114 and outputs the result. The pulse width of the PWM waves P2-P4 is controlled depending on the D3-D5 by 1 LSB. Thus, the PWM wave corresponding to the D1, D2 and the PAM wave corresponding to the D3-D5 are outputted at a terminal 135.

Filed: 1989-06-23
Abstract: PURPOSE:To monitor state the write to a magnetic stripe of a card provided with the magnetic stripe is performed in a uniform information density by arranging plural sensors at regular intervals in the advancing direction of the card. CONSTITUTION:When a transfer speed of the magnetic card 1 is changed during the write, the information density on the magnetic stripe 2 is largely changed, and afterward the infeasibility of the read may happen. Thus, it is necessary to confirm that the transfer of the magnetic card 1 is performed at a constant speed during the write. Consequently, photosensors 11-15 in pairs of light emitting elements and light receiving elements are arranged at regular intervals for the purpose of detecting a leading edge of the magnetic card 1 in the advancing direction of the card 1. Then, by monitoring each passing time between the photosensors when the leading edge of the magnetic card 1 is transferred, whether the magnetic card 1 is transferred at a constant speed can be confirmed.
